Storing a value at a given time and comparing it to another value obtain 5 second later. If the second value is grater do …… and if the second value is lesser do …… If anyone can help I will be very grateful. Thanks

You can use a timer to control the En input to this function or if you can get an external triger to synchronize the measurement by using one of the digital inputs connection it to the En of the function.
